Typedef Documentation
typedef void *(* rte_port_in_op_create) (void *params, int socket_id)
Input port create
Parameters
params Parameters for input port creation
socket_id CPU socket ID (e.g. for memory allocation purpose)
Returns
Handle to input port instance
Definition at line 65 of file rte_port.h.
typedef int(* rte_port_in_op_free) (void *port)
Input port free
Parameters
port Handle to input port instance
Returns
0 on success, error code otherwise
Definition at line 75 of file rte_port.h.
typedef int(* rte_port_in_op_rx) (void *port, struct rte_mbuf **pkts, uint32_t n_pkts)
Input port packet burst RX
Parameters
port Handle to input port instance
pkts Burst of input packets
n_pkts Number of packets in the input burst
Returns
0 on success, error code otherwise
Definition at line 89 of file rte_port.h.
typedef int(* rte_port_in_op_stats_read) (void *port, struct rte_port_in_stats *stats, int clear)
Input port stats get
Parameters
port Handle to output port instance
stats Handle to port_in stats struct to copy data
clear Flag indicating that stats should be cleared after read
Returns
Error code or 0 on success.
Definition at line 107 of file rte_port.h.
typedef void *(* rte_port_out_op_create) (void *params, int socket_id)
Output port create
Parameters
params Parameters for output port creation
socket_id CPU socket ID (e.g. for memory allocation purpose)
Returns
Handle to output port instance
Definition at line 139 of file rte_port.h.
typedef int(* rte_port_out_op_free) (void *port)
Output port free
Parameters
port Handle to output port instance
Returns
0 on success, error code otherwise
Definition at line 149 of file rte_port.h.
typedef int(* rte_port_out_op_tx) (void *port, struct rte_mbuf *pkt)
Output port single packet TX
Parameters
port Handle to output port instance
pkt Input packet
Returns
0 on success, error code otherwise
Definition at line 161 of file rte_port.h.
typedef int(* rte_port_out_op_tx_bulk) (void *port, struct rte_mbuf **pkts, uint64_t pkts_mask)
Output port packet burst TX
Parameters
port Handle to output port instance
pkts Burst of input packets specified as array of up to 64 pointers to struct rte_mbuf
pkts_mask 64-bit bitmask specifying which packets in the input burst are valid. When pkts_mask bit n
is set, then element n of pkts array is pointing to a valid packet. Otherwise, element n of pkts
array will not be accessed.

Parameters
port Handle to output port instance
stats Handle to port_out stats struct to copy data
clear Flag indicating that stats should be cleared after read
Returns
Error code or 0 on success.
